The design evolution within Yanmar's technology creates engines which not only perform, but also last and last. That's our mission. This has led to a worldwide reputation for unsurpassed reliability. These engines are the most compact and powerful in their class. The 24-valve overhead cam valve train is the main driver of this success. And, not to forget, the water cooled wastegated turbocharger, intercooler and fuel cooler, which maintain peak performance.

Initially designed for Alaskan fisherman, Luggers are well known by commercial and pleasure craft operators for their long life and smooth, quiet operation.
The L1064T1 features a mechanical fuel delivery system and liquid cooled turbocharger for enhanced fuel effeciency. Ideal fo rthe commercial operator who runs full-throttle for long periods, the L1064T1 is designed for long hours and simplified maintenance.
All the 1064 diesel engines are US EPA Tier II compliant with an in-line design tht makes them perfect repower engines for older in-line six cylinder machines.
The Lugger 1064 (106 mm bore-4 cylinder), 4.5 liter, diesels have heavy-duty tractor blocks. This high torque design provides a strong foundation; but a marine engine is only as good as its marinization. A Lugger's marinization is cast iron tough. The expansion tank and liquid-cooled exhaust manifold are cast iron. Some engines only use bypass water to cool their manifolds. Lugger integrates the two pass manifold into the cooling system main stream to assure even temperature control and to eliminate hot spots that can stress metal components.

Yanmar's engines last and last. They are designed and built to do just that. Every detail is taken Into account. Take for instance the stainless steel exhaust/water mixing elbow: a guarantee for long life and corrosion resistance. This tough engine is built to perform. The turbocharger with wastegate and inlercooler improves acceleration on the higher output model even further. This is best-in-dass diesel power from Yanmar.
